This application is a continuation of U.S. patent application Ser. No. 11/194,298, filed Aug. 1, 2005 which is a continuation of U.S. patent application Ser. No. 10/455,624, filed Jun. 6, 2003, which claims priority to U.S. Provisional Pat. App. No. 60/438,889, filed Jan. 9, 2003.
The present invention relates to mounts for interface devices such as computer monitors and televisions. In particular, the present invention relates to a mount which allows the interface to be tilted about a generally horizontal pivot axis.
The development of flat panel computer monitors and flat screen televisions offers the opportunity to replace large computer monitors and large television sets with displays having the same screen area but only a small fraction of the depth and weight. This allows computer monitors to be placed on desks without consuming a large portion of the desk top space. Similarly, flat screen televisions can be placed in locations which were previously not practical locations.
The light weight and thin profile of the flat panel monitors and televisions allows them to be supported on a relatively small base, be hung on a wall, or to be supported by a support system which is connected to a mounting surface such as a wall, a post, or a top, bottom, or side surface of a desk or cabinet. The ability to adjust the orientation of the flat panel display with respect to the viewer is a desirable feature. There is a need for mounting systems which will allow adjustment of the position and the orientation of the display. The support systems should be simple and easy to use, and should be stable so that the display remains in the position and orientation selected.
A mounting system for an interface device such as a flat panel display (such as a computer monitor or television) allows the display to be tilted about a horizontal pivot axis which passes through a center of gravity of the display. The system includes a support and a mount which are connected together so that they can slide with respect to one another through an arc path which has the pivot axis at its center. The mount is attached to the back side of the display, while the support is connected directly or indirectly to a support surface.
The display can be tilted about the pivot axis, which is parallel to the front surface of the display, through a range of angles defined by the arc. Because the pivot axis passes through the center of gravity of the display, the weight of the display is balanced in any one of the angular positions. No clamping or other adjustment is required to hold the display in any one of its tilted positions.
Mounting system 10 has three major parts, mount bracket 14, support or wall bracket 16, and a pair of glides 18. Mount bracket 14 is attached to a back surface of monitor 12, while support 16 is connected either directly or indirectly to a support surface such as post P (or a wall).
Mount bracket 14 has a pair of arcuate slots 20 which define the range of sliding motion of mount bracket 14 with respect to support bracket 16. Glides 18 are carried by support bracket 16 and project into slots 20. Glides 18 ride within slots 20 to allow a sliding movement of mount 14 with respect to support 16. The path of the sliding movement is defined by the arc of slots 20. In the embodiment shown in
The arc defined by slots 20 is a portion of a circle having its center defining a horizontal pivot axis 22. As shown in
The present invention provides a very simple and inexpensive mounting system which allows tilting of display 12 over a wide range of tilt angles. Although the embodiment shown limits the range of tilt angles to approximately 50 degrees, the range could be either larger or smaller depending upon the length of the arc defined by slots 20.
As shown in
Support 16 is a generally U-shaped bracket formed base 50, right side wall 52R, and left side wall 52L. Mounting slots 54 and 56 are used to connect support 16 to a wall, a post, or other support. As seen in
As shown in
As shown in
The inner end of dog bone 112 is pivotally connected to side knuckle 114 by tapered bearing 122. Adjustment screw 124 controls the drag of taper bearing 122 to control the rotation of dog bone 112 with respect to side knuckle 114.
The outer end of dog bone 112 is pivotally connected to the inner end of dog bone 110 by tapered bearing 126. Adjustment screw 128 controls the frictional drag produced by tapered bearing 126, and can be used to lock dog bones 112 and 110 in a fixed orientation if desired.
The outer end of dog bone 110 is pivotally connected by tapered bearing 130 to side knuckle 108. Adjustment screw 132 is used to adjust drag or to lock dog bone 110 and side knuckle 108 together as desired.
Support assembly 106 is attached by screws to the side arm of side knuckle 108.
Support 106 forms a sliding connection with mount 104. As in the first embodiment of the present invention, the sliding connection is defined by an arc segment of a circle which has a center defining a pivot axis of display 102. The pivot axis is positioned at or very near the center of gravity of display 102, so that display 102 is weight-balanced in the various tilt positions.
Mount 104 is attached by screws to the back surface of display 102. Because of the balance of weight about the virtual pivot axis defined by mount assembly 104 and support assembly 106, display 102 can be tilted through a range of positions as illustrated in
Mount assembly 104 includes arch 140 and mounting plates 142 and 144. Mounting plate 142 is attached to one end of arch 140 by a pair of screws, and mounting plate 144 is attached to the opposite end of arch 140 by a pair of screws. Arch 140 defines an arc having as its center the virtual pivot axis which passes horizontally through display 102. Outer surface 146 has beveled edges 148 along its longitude and latitude. Similarly, inner surface 150 of arch 140 has beveled edges 152. Beveled edges 152 form parallel guide tracks for the sliding movement of arch 140 with respect to support assembly 106.
Support assembly 106 includes yoke 160, dowels 162, 164, and 166, and wheels 168, 170 and 172. Each of the dowels 162, 164, 166 includes a pair of wheels 168, 170, 172, respectively, for riding on beveled edges of arch 140. Wheels 168 are mounted on opposite ends of dowel 162 to ride on beveled edges 148. Wheels 170 are mounted on dowel 164 to ride on beveled edges 152. Wheels 172 are mounted on dowel 166 and ride on beveled edges 148. Thus arch 140 is captured between the three sets of rollers 168, 170, and 172 while permitting a sliding movement
Both embodiments (10,100) of the present invention feature an arcuate sliding movement of a mount (14,104) with respect to a support (16,106). This defines a pivot axis about which the display (12,102) is tilted. The weight-balanced relationship of the display with respect to the pivot axis allows the display to be stable without clamping in any of the range of tilt angles. Thus a simple, easy-to-use tilt adjustment is provided.
As in the other embodiments, the arc defined by the slots 320 is a portion of a circle having its center defining a horizontal pivot axis 322. This virtal pivot axis will pass through a center of gravity of display 302. As a result, the weight of display 302 remains balanced about pivot axis 322, regardless of the tilt angle. Maintaining the display 302 in a balanced state allows easy adjustment by a user with minimal force. Once positioned, the display 302 will remain in that position.
Given the minimal force required to adjust the display 302, locking mechanism 324 can be incorporated as part of mounting system 300. Locking mechanism 324 secures display 302 in place once display 302 has been positioned. Locking mechanism 324 secures display 302 by securing mount bracket 310 in place with respect to support bracket 312. While locking mechanism 324 is not required to maintain display 302 in place, locking mechanism 324 helps avoid the display 302 from being re-positioned due to inadvertent contact. The user does not have to support or hold display 302 in place while tightening the locking mechanism 324. When multiple mount brackets 310 are used together, the locking mechanism 324 is preferably positioned to face outward rather than toward the middle of the display 302 for easy access by the user to tighten the locking mechanism 324. A similar type of locking mechanism could also be incorporated with the earlier described mounting systems 10, 100.
The use of multiple glides 314 on each side of support bracket 312 could similarly be incorporated into the embodiments described by
Support bracket 312 includes a hook 334 at its top and a flange 336 at its bottom. The hook 334 is placed on a rail 338 at the top of the support plate or base 316. Once the hook 334 is secured on the rail 338, flange 336 fits beneath rail 340 at the bottom of support plate 316. Flange 336 preferably includes a threaded through hole 342 that will accept a set screw 343 that can be secured against the bottom rail 340. Tightening the set screw will help avoid the support bracket 312, and thus the display 302, from being pulled out from the support plate 316 or sliding laterally along the rails 338 and 340. Support bracket 312 and support plate 316 allow the display 302 to be slid or repositioned laterally along the rails 338 and 340 once the hook(s) 334 are placed on the rail 338. The support plate 316 also includes a series of openings 372 that allow for mounting support plate 316 to a wall. A number of different methods may be employed for mounting the support plate 316 to the wall, including differently shaped and spaced openings.
Mount 310 includes slots 344 that provide flexibility in securing display 302 to mount bracket 310. Alternate mounting techniques or patterns could also be used to secure the display 302 to the mount bracket 310.
A similar locking mechanism as described above in the previous embodiment can also be incorporated into the earlier embodiments described in
